Linux Lite
@elfprince suggested that I give Linux Lite a try, saying that it might be a pleasant surprise for me.
At first glance, it appears very well produced. It's based on Ubuntu, so there should be no question about the availability of needed packages. It's been a long, dry spell for distros that I would consider spending some extended time with, so I hope Legolas is right about the pleasant surprise.
Here's all I know about Linux Lite so far (from their download page):
"By producing an easy to use Linux based Operating System, we hope that people will discover just how simple it can be to use Linux Lite.
Linux Lite is free for everyone to use and share, and suitable for people who are new to Linux or for people who want a lightweight environment that is also fully functional.
Linux Lite is based on the Ubuntu LTS series giving you 5 years of support per major release.
The following software is included: LibreOffice Suite, VLC Media Player, Firefox Web Browser, Thunderbird Email, Gimp Image Editor, Lite Themes, Lite User Manager, Lite Software, Lite Sounds, Lite Tweaks, Lite Welcome, Lite Manual, Lite Sources, Lite Updates Notify, Lite Upgrade, Whiskermenu and more.
Laptop/Ultrabook/Netbook users: If the screen locks during Live mode, type 'linux' into the user box and click on the Login button (no password required)"
@tomscharbach , it's possible that this is the Linux distro you've been looking for, as something for Windows users to understand easily (in place of Zorin).
